How does Tempdrop work?

The Tempdrop wearable sensor is designed to be worn comfortably under your upper arm while you sleep, secured in place with a soft, elastic armband. Each night, the sensor collects thousands of data points, including your body temperature, environmental factors, and sleep movement.

Every morning, after removing the sensor, simply sync it to the Tempdrop app (available on the Apple Store and Google Play) using Bluetooth Low-Energy (BLE). This will retrieve your sleep temperature results and sleep data. Tempdrop takes the hassle out of traditional BBT (basal body temperature) tracking, allowing you to get accurate results without losing sleep.

The app also provides a fertility charting feature to track all your other fertility symptoms along with BBT which is automatically added to your chart. The sensor and app together provide an all-in-one ovulation tracking solution.
